Description

Technical Field

[0001] This utility model relates to the technical field of connectors, and specifically discloses a sealing structure for the male and female connector connection and a connector. Background Technology

[0002] Connectors, as essential components for achieving electrical connections or signal transmission, are widely used in electronic equipment, communication systems, industrial automation, and other fields. Their primary function is to connect and disconnect conductive terminals through the mating of male and female connectors, thereby ensuring stable transmission of current or signals. With the continuous development of modern electronic technology, the operating environments of connectors are becoming increasingly complex, placing higher demands on their sealing performance, reliability, and durability. Especially in special application scenarios such as outdoor equipment, marine equipment, and industrial automation equipment, connectors need to possess excellent waterproof, dustproof, and salt spray resistance properties to ensure the normal operation of equipment in harsh environments.

[0003] Existing circular connectors (such as the M8 specification) typically use a sealing ring between the nut and the thread at the male-female connection for sealing. (See...) Figure 1 While this design can achieve a certain degree of sealing, it has significant shortcomings. Because the sealing ring achieves its seal through compression caused by the rotation of the nut, the tightening process generates shear and torsional forces on the sealing ring. This can easily lead to wear, deformation, or even displacement of the sealing ring, reducing its sealing performance and potentially causing seal failure. Especially under conditions of frequent insertion and removal, prolonged use, or harsh environments (such as high humidity, high salt spray, and sandstorms), the reliability of this sealing structure will further decrease, severely impacting the connector's lifespan and the normal operation of the equipment.

[0004] Therefore, given the obvious defects in the sealing structure at the male and female connector connection in the existing technology, there is an urgent need for a new sealing structure that can effectively solve the above problems, so as to improve the sealing performance, reliability and service life of the connector, and enable it to better adapt to various complex working environments. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sealing structure for the male and female connector connection and a connector.

[0006] On the one hand, this utility model discloses a sealing structure for the male and female connector connection, which adopts the following technical solution:

[0007] A sealing structure for the male-female connector connection is disclosed. The connector includes a male and a female. The male has a pin seat, and the female has a socket seat that can be inserted into and removed from the pin seat. A nut is sleeved on the pin seat of the male. A threaded ring is provided on the outer periphery of the socket seat of the female. A female groove is formed between the threaded ring and the socket seat. A first sealing ring is provided in the female groove. When the male and female are inserted, the pin seat is inserted into the female groove, and the nut and the threaded ring screw together, causing the end of the pin seat to press against the first sealing ring.

[0008] Preferably, the outer periphery of the pin socket is provided with a second sealing ring, and when the male head and the female head are inserted, the end of the threaded ring squeezes the second sealing ring.

[0009] Preferably, the outer periphery of the pin holder is provided with a second annular positioning groove, and the second sealing ring is sleeved in the second annular positioning groove.

[0010] Preferably, the threaded ring has an annular protrusion on the side opposite to the male end, and when the end of the pin seat presses against the first sealing ring, the annular protrusion and the end of the nut have a clearance gap.

[0011] Preferably, the outer periphery of the socket is provided with a first annular positioning groove, and the first sealing ring is sleeved in the first annular positioning groove.

[0012] On the other hand, this utility model discloses a connector, which includes a male head, a female head, and a sealing structure applied to the male and female head connection of the connector.

[0013] Preferably, the male connector includes a male connector body and a male connector housing, the male connector body is fixed inside the male connector housing, and a third sealing ring is provided between the male connector body and the male connector housing; the female connector includes a female connector body and a female connector housing, the female connector body is fixed inside the female connector housing, and a fourth sealing ring is provided between the female connector body and the female connector housing.

[0014] Preferably, the male head body is provided with a third annular positioning groove for accommodating the third sealing ring; the female head body is provided with a fourth annular positioning groove for accommodating the fourth sealing ring.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] This solution replaces the male connector with a nut and the female connector with a threaded part. A first sealing ring is placed in the groove between the female connector's socket and the outer threaded ring. When the male and female connectors are inserted, the first sealing ring is compressed by the end of the pin socket and fits snugly within the concave cavity of the female connector's groove. Because the first sealing ring is only subjected to compressive force, rather than linear compression caused by nut rotation, this effectively avoids the sealing failure problem caused by nut rotation in traditional connector sealing structures, thus improving the sealing level.

Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] This embodiment discloses a sealing structure for the male and female connector connection and a connector, and its operation... Figure 2-5 The connector includes a male connector 1 and a female connector 2. The male connector 1 includes a male connector housing 12 and a male connector body 11 fixed inside the male connector housing 12. The female connector 2 includes a female connector housing 22 and a female connector body 21 fixed inside the female connector housing 22. The male connector body 11 has a pin socket 111 and the female connector body 21 has a socket 211 that can be matched and inserted into the pin socket 111.

[0026] In this design, the male connector body 11 has a nut 13 fitted over its pin seat 111, and the female connector body 21 has a threaded ring 23 on its outer periphery of its socket seat 211. A female connector groove 231 is formed between the threaded ring 23 and the socket seat 211, and a first sealing ring 3 is provided in the female connector groove 231. When the male connector 1 and the female connector 2 are inserted, the pin seat 111 is inserted into the female connector groove 231, and the nut 13 and the threaded ring 23 are screwed together, causing the end of the pin seat 111 to press against the first sealing ring 3, thereby achieving a seal at the male and female connector connection. This design cleverly places the first sealing ring 3 in the female connector groove 231, achieving a seal through the pressing of the end of the pin seat 111, rather than relying on the line-direction pressing caused by the rotation of the nut. This effectively avoids the problem of seal failure caused by nut rotation, significantly improving the stability and reliability of the seal. Even under frequent insertion and removal and long-term use, it can still maintain a good sealing effect, significantly extending the service life of the connector, and is especially suitable for harsh environments such as high humidity, high salt spray, and sandstorms.

[0027] As a preferred embodiment, the threaded ring 23 has an annular protrusion 24 on the side opposite to the male head 1. When the end of the pin seat 111 presses against the first sealing ring 3, a clearance gap is left between the annular protrusion 24 and the end of the nut 13. The annular protrusion 24 can make the female head structurally stronger and also facilitates the user to use the position of the annular protrusion 24 for leverage during insertion and removal. The clearance gap ensures that even if the first sealing ring 3 experiences elastic fatigue after prolonged use, the nut 13 can continue to be screwed into the clearance gap to press against the first sealing ring 3, thereby maintaining good sealing effectiveness.

[0028] As a preferred option, refer to Figure 5 The pin socket 111 has a second sealing ring on its outer periphery. When the male connector 1 and the female connector 2 are inserted, the end of the threaded ring 23 presses against the second sealing ring 4. By setting the second sealing ring 4, the sealing effect at the connection between the male and female connectors is further enhanced, forming a double sealing structure, which makes the sealing more reliable, better adaptable to complex working environments, and extends the service life of the connector.

[0029] As a preferred embodiment, the pin socket 111 has a second annular positioning groove on its outer periphery, and the second sealing ring 4 is fitted into the second annular positioning groove. The second annular positioning groove can effectively position the second sealing ring, ensuring that the second sealing ring will not shift during the insertion process, thereby ensuring the stability of the sealing effect and further improving the sealing performance of the connector. Correspondingly, the socket 211 has a first annular positioning groove on its outer periphery, and the first sealing ring 3 is fitted into the first annular positioning groove. The first annular positioning groove can effectively position the first sealing ring 3, ensuring that the first sealing ring 3 remains stable during the insertion process, thereby improving the reliability of the seal. However, in this embodiment, the first annular positioning groove is not designed. Since the female head groove 231 has a certain depth, the first sealing ring 3 is elastically tightened outside the socket 211, and the first sealing ring 3 is not easy to fall out. Therefore, the first annular positioning groove can also be omitted.

[0030] As a preferred option, refer to Figure 5 A third sealing ring 5 is provided between the male connector body 11 and the male connector housing 12, and the male connector body 11 has a third annular positioning groove for accommodating the third sealing ring 5; a fourth sealing ring 6 is provided between the female connector body 21 and the female connector housing 22, and the female connector body 21 has a fourth annular positioning groove for accommodating the fourth sealing ring 6. The provision of the third sealing ring 5 and the fourth sealing ring 6 can further improve the overall sealing performance of the connector, preventing impurities such as liquid or dust from entering the connector interior through the gaps between the male connector body 11 and the male connector housing 12, and between the female connector body 21 and the female connector housing 22, thereby improving the protection level of the connector and enabling it to better adapt to harsh working environments.

[0031] The technical solution provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
